T0 (LZ/Z w'l/O'nt '1T/2. 777,601/ concern: Be it known that 1, ROBERT 7. W. CLARK, a j screw-threaded Jfor holding engagement with The upper end 12 of the bolt 9 is also citizen of the United States, residing at Bufl the ceiling.

Jfalo, in the county of Erie and State of New York7 have invented certain new and useful improvements in Pipe-Hangers; and 1 do hereby declare the `following to be a i'ull, clear,

' in holding positionaround the pipe.

13 is a second jaw, pivoted to the first jaw, itslower end overlapping the iirst jaw when Its upper end has the shank 14, provided with the and exact description of' the invention, such open slot 15, adapted to register with the as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or 'ligures of reference marked. thereon., which form a part of this specification.

lviy invention relates to improvements in pipe-hangers, and more particularly to that type involving overlapping jaws having lockable shanks.

The object oi my invention is to provide a simple construction in which the jaws can be quickly and easily locked around the pipe or released therefrom.

To that end my invention consists, essensentially, of' a suspending-jaw, an elongated shank on such jaw provided with a closed slot, a second jaw pivoted to the iirst jaw, a shank on such second jaw provided with an open slot adapted to register with the closed slot of the iirst jaw, a locking-pin riding in the closed slot and adapted for locking engagement with the open slot of the second jaw and releasing disengagement therefrom, and means for securing the first jaw to the ceiling'.

1n the drawings, Figure 1 is an end elevae tion oi? my improved pipe-hanger in locked position; and hig. 2 is a side elevation of the same, showing the unlocked position off the jaws in4 dotted lines. I

Referring to the drawings, 1. is a suspending-jaw having the elongated shank 2, pro'- vided with the shoulder 3 and the longitudinal closed slot 4. The upper end of shank 2 is provided with the conical head 5, which rests looselyin the conical seat 6 of the open cage 7. ln the upper end of the cage 7 is the cylindrical oriiice 8, adapted for 'the loose passage therethrough of the belt 9, its lower serew-threaded end 10 being in adjustable engagement with the nut 11 within the cage closed slot 4 of jaw 1.

16 is a locking-pin riding in the closed slot 4 of jaw 1, having at one end the integral head 17 and at its other end the removable head 13. These heads 17 and 18 ride in eountersunk grooves 19, 19, and 20, sur-l rounding the closed slot 4 of jaw 1 and the open slotI 15 of jaw 13.

1n operation when the jaws 1 and 13 are in closed position the locking-pin 16 rests in the lower ends of the vregistering slots 4 and 15 in the jaws, which serves to hold such jaws securely around the suspended pipe. 1n order to release the jaws 1 and 13 from locked position around the pipe, it is only necessary to raise the locking-pin 16 out of the open' slot 15 in the jaw 13 and into the upper end oi' the closed slot 4 in the jaw 1. The pivoted jaw 13 can then be swung to one side out of engagement with the pipe to release the same, as clearly shown in dotted lines in Fig. 2.

The countersinking of the heads 17 and 18 of the pin 16 prevents the accidental dislodgement of such pin from its locking position in the registering slots 4 and 15.

1 claim- 1. A pipe-hanger consisting essentially of a suspending-jaw, an elongated shank on such jaw provided with a closed slot, a second jaw pivoted to the iirst jaw, a shank on such second jaw provided with an open slot adapted to register with the closed slot oi' the i'irst jaw, a locking-pin riding in the closed slot and adapted for locking engagement i with the open slot of the second jaw and releasing disengagement therefrom and means for securing the first jaw to the ceiling, all combined and operating as and for the purpose stated.

2. A pipe-hanger consisting essentially of a suspending-jaw, an elongated shouldered IOO y Jaw and overlapping closed slot, a second jaw pivoted to the 'first the lirst jaw to the ceiling, all combined and 1o the saine, an upper operating-as and for the purpose stated.
